I'm not going to tell you what he borrowed, and neither is he. You see, he's running a small contest.
Eric's story "Rejiggering the Thingamajig" was published by Analog last year, and now Escape Pod has put up a free audio version. There's a free text version up on that page as well. Read the story or listen to it, whichever, and figure out what it was that Eric borrowed from the Schlockiverse.
Now head over to the form on Eric's site, give him your name, email address, and your answer, and if your answer is one of the correct ones you'll be entered into a drawing to win a collection of his stories and a Schlock Mercenary book of your choice. The contest closes on February 28th.
Need further enticement? The first line of "Rejiggering the Thingamajig" reads as follows:
The teleport terminal had not been built with tyrannosaurus sapiens in mind.
In the spirit of shameless borrowing, it's possible I may just steal "tyrannosaurus sapiens" for the Schlockiverse. But not until the contest is over, since that would skew your answers.
